After correcting the original service problem, perform the following
safety checks before releasing the set to the customer :

1. Check the area of your repair for unsoldered or poorly-soldered

connections. Check the entire board surface for solder splashes
and bridges.

2. Check the interboard wiring to ensure that no wires are “pinched”

or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors,

that were installed during a previous repair. Point them out to the
customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs of

deterioration. Point them out to the customer and recommend their
replacement.

5.  Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270°C during

repairing.

• Do not touch the soldering iron on the same conductor of the cir

cuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or

unsoldering.
